Contexte et objectif – Les patients âgés gonarthrosiques présentent une dégradation du contrôle postural. Les méthodes non pharmacologiques sont aujourdhui recommandées comme option de première intention dans la gestion de l’arthrose. L’hydrothérapie fait partie des moyens de rééducation à disposition des patients âgés atteints d’arthrose du genou pour ses effets antalgiques et musculaires. Cependant, peu d’études sont actuellement disponibles concernant l’effet de l’hydrothérapie sur le contrôle postural, associée ou non à des programmes de rééducation individuels ciblés. Par ailleurs, le contrôle postural est susceptible de variations diurnes. Cette étude a eu pour objet de décrire le contrôle postural des personnes gonarthrosiques à quatre périodes de la journée, puis de comparer l’amélioration du contrôle postural au cours de deux programmes de rééducation différents recourant à l’hydrothérapie. Matériel et méthodes - Deux-cent-quatre-vingt quatre patients souffrant d’arthrose du genou ont été inclus dans cette étude. Le bilan posturographique a été réalisé une semaine avant la cure thermale en condition simple (yeux ouverts, support stable) et en conditions sensorielles contradictoires (vision faussée ou indisponible, proprioception perturbée). Pour évaluer les variations diurnes de la stabilité posturale, les patients ont été randomisés à quatre périodes d’essai dans la journée définies comme suit : 8h-10h, 10h-12h, 13h-15h, 15h-17h. L’influence du sexe, de l’âge, de la taille, du poids et de l’indice de masse corporelle sur la stabilité posturale a été évaluée. La gonalgie a également été évaluée à quatre périodes d’essai. Par la suite, les patients ont été randomisés en deux groupes de rééducation différents pour recevoir des traitements aquatiques : groupe cure classique (hydrothérapie efficace prouvée, c’est-à-dire groupe témoin) et groupe cure active (hydrothérapie combinant des programmes de réhabilitation individuels ciblés). Les bilans de posturographie statique ont été réalisés respectivement à 21 jours, 42 jours et 90 jours après le début de l’hydrothérapie. Résultats –Les tests posturographiques ont été réalisés chez 241 patients (âge moyen : 64,8 + 8,7 ans ; 82 hommes). Le contrôle de l’équilibre était plus efficace l’après-midi que le matin à la fois dans les conditions simple (p = 0,012) et sensorielle contradictoire (p = 0,047), en particulier en début d’après-midi lorsque la vision et la proprioception étaient disponibles (p = 0,026) ou perturbées (p = 0,019). La gonalgie a été plus prononcée le matin que l’après-midi (p < 0,001). La variation diurne du contrôle postural était plus marquée chez les patients plus âgés, de poids plus élevé, de sexe masculin, dans les conditions d’essais différentes (p < 0,05). Les deux cures d’hydrothérapie ont eu des effets curatifs considérables sur la restauration du contrôle de l’équilibre. Une meilleure précision des oscillations posturales a été constatée dans le groupe cure active par rapport au groupe cure classique, 42 jours après le début de l’hydrothérapie (p = 0,020), en particulier lorsque la proprioception a été perturbée avec (p = 0,028) ou sans (p = 0,025) vision disponible. Dans les deux groupes a été observée une stabilité posturale comparable dans un délai de trois mois. Conclusions - Cette étude a montré une meilleure stabilité posturale chez les patients atteints d’arthrose du genou, en début d’après-midi par rapport à la fin de matinée dans les situations sensorielles simples ou contradictoires. Il a été constaté que ces variations étaient également liées à l’âge, au sexe, au poids et pourraient être expliquées par la douleur articulaire fluctuante dans la journée. Considérée comme un traitement non pharmacologique applicable et recommandé, l’hydrothérapie est bénéfique à l’amélioration de la stabilité posturale chez les patients âgés atteints d’arthrose du genou, en particulier combinant un programme de réhabilitation individuel ciblé. [...] / Background and Objective – Increasing evidence supports balance control impairment in elderly patients with knee osteoarthritis (OA). Current guidelines recommend non-pharmacologic methods as first-line options in the management of OA. Hydrotherapy is a beneficial training medium for rehabilitation in elderly knee OA patients. However, few indications at present are available concerning the effect of hydrotherapy combining with targeted individual rehabilitation programs to improve balance control. Meanwhile, there is limited data on diurnal variation of balance control in these patients. This study aimed to investigate postural stability in elderly patients with symptomatic knee OA during different periods in a daytime before the spa therapy, then to study the results obtained before and after hydrotherapy to compare the improvement of balance control in these patients in two different water-based rehabilitation programs. Materials and Methods – Two-hundred and eighty-four knee OA patients were enrolled in this study. Static posturography using a vertical force platform was performed one week before spa therapy in simple (eyes open, firm support) and conflicting sensory (vision altered or unavailable, proprioception altered) conditions. To assess diurnal postural variations, patients were randomized to four testing sessions in a daytime defined as follows: 8-10am, 10-12am, 1pm-3pm, 3pm-5pm. Influence of sex, age, height, weight, and body mass index on postural stability was evaluated. Knee pain was also assessed in four testing sessions. Patients were then randomized to two different rehabilitated groups to receive spa therapies. Classic treatment group as a control received the efficacy proven spa water therapy, and active treatment group received spa water therapy combining with targeted individual rehabilitation programs. Static posturographies were carried out respectively in 21 days, 42 days and 90 days after the beginning of hydrotherapy. Results – Posturographic tests were completed for 241 patients (mean age: 64.8 + 8.7 years; 82 males). Balance control was more efficient in the afternoon than in the morning both in simple (p = 0.012) and conflicting sensory conditions (p = 0.047), especially in early afternoon when vision and proprioception were available (p = 0.026) or disturbed (p = 0.019). Patients’ knee pain was more pronounced in the morning than in the afternoon (p < 0.001). Diurnal variation of balance control was more noticeable in older, heavier, and male patients under different testing conditions (p < 0.05). Both the water-based therapies had considerable curative effect on balance control restoration. Better postural sway precision were found in active group than classic group 42 days after the beginning of hydrotherapy (p = .020), especially when proprioception was interfered with (p = .028) or without (p = .025) an available vision. Both of the groups have been observed a comparable postural stability in a three-month term. Conclusions – This study showed that better postural stability was observed in patients with knee OA in early afternoon than in late morning in simple and conflicting sensory situations. These variations appeared also to be related to age, sex, and weight and could be explained by fluctuant joint pain in a daytime. As feasible and recommended non-pharmacologic treatment, hydrotherapy is beneficial to the improvement of postural stability in elderly patients with knee OA, especially combining with targeted individual rehabilitation programs. These findings are important for future studies aiming at enhancing postural stability in knee OA patients and should be taken into account in the management of knee OA to generate applicative approaches to prevent the occurrence of adverse events in patient’s daily life.

Fragestellung: Mögliche Interaktionen zwischen Mittelohrdruck und Gleichgewichtsstörungen werden seit vielen Jahren diskutiert. Der Rolle der druckausgelösten Trommelfellbewegungen, die bei degenerativ fixierten Ossikelgelenken aufgrund des Hydraulikfaktors eine viel grössere Kraft ausüben als der direkte Druck an den Innenohrfenstern, wurde dabei nur geringe Aufmerksamkeit gewidmet. Patienten und Methodik: Wir untersuchten bei 19 Patienten mit einseitigem Morbus Ménière die durch wechselnde Drucke im äusseren Gehörgang (analog zur Tympanometrie) ausgelösten Interaktionen zwischen Trommelfellauslenkungen und vestibulären Reaktionen in der Elektronystagmographie und in der Posturographie. Ergebnisse und Schlussfolgerungen: Bei schnellen und langsamen Druckwechseln konnten zwischen –600 und +400 daPa weder auf dem gesunden noch auf dem erkrankten Ohr im Elektronystagmogramm Nystagmen nachgewiesen werden. Die posturographische Aufzeichnung der vestibulospinalen Reaktionen auf einer Luzerner Messplatte erwies sich dagegen als sensibler. Die Längenzunahme der Schwankungslinie zeigte bei beiden durchgeführten Druckwechseln auf dem kranken Ohr signifikante Unterschiede gegenüber der Messung bei Reizung des gesunden Ohres. Diese Methode ist somit der klassischen Prüfung des Hennebertschen Fistelsymptoms überlegen. Das vestibulospinale System reagiert möglicherweise empfindlicher als das vestibulookuläre auf Druckschwankungen der Perilymphe. Darüber hinaus könnte der nachgewiesene Zusammenhang der druckausgelösten Trommelfellbewegungen mit cochleovestibulären Symptomen bei einigen Patienten mit M. Ménière den Erfolg einer Paukenröhrcheneinlage erklären, da hiermit aussendruckinduzierte Trommelfellbewegungen und damit verbundene Perilymphschwankungen von vornherein unterbunden werden. / Objectives: Interactions between middle ear pressure and vestibular disturbances have been discussed for many years. Less attention has been paid to the influence of ear drum movements caused by pressure changes in the external auditory meatus. Because of the hydraulic amplification in case of fixed ossicular joints the impact of these movements is bigger than the direct pressure on the internal ear windows. Material and Patients: We examined the interaction between ear drum movements and vestibular reactions caused in the external auditory meatus of 19 patients suffering from unilateral Ménière’s disease. Results and Conclusions: Both fast as well as slow pressure changes between –600 and +400 daPa were not able to induce nystagmus in the electronystagmogram of either the healthy or the damaged ear. Posturographic recordings of the vestibulospinal responses on the ‘Luzerner measuring platform’ were significantly more sensitive. The increase in length of the postural staggering line showed significant differences between the healthy and the damaged ear for fast and for slow pressure changes compared to calibration. In conclusion, the sensitivity of this examination is superior to the classical examination of Hennebert’s fistula symptom. The vestibulospinal system is more sensitive towards pressure changes of the perilymph than the vestibuloocular system. The proven correlation between ear drum movements and internal ear symptomatology could explain the success of the treatment of patients suffering from Ménière’s disease with tympanic grommets. Thus grommets prevent the pressure-induced ear drum movements and avoid perilymph movements induced by pressure changes. / Chez les patients souffrant de la maladie de Ménière, les variations de pression entraıˆnent des mouvements du tympan, influant ainsi sur les réactions vestibulaires. Objectifs: Si l’on s’est longtemps intéressé aux possibles interactions entre la pression de l’oreille moyenne et les troubles de l’équilibre, on a en revanche prêté moins d’attention à l’influence que peuvent exercer les mouvements du tympan dus aux variations de pression dans le conduit auditif externe. Or, lorsque les articulations ossiculaires sont bloquées, l’amplification hydraulique fait que ces mouvements ont un impact plus important que la pression directe exercée aux fenêtres de l’oreille interne. Méthodes et patients: Chez 19 malades souffrant d’un syndrome de Ménière unilatéral, nous avons étudié par ENG et posturographie la relation entre les réactions vestibulaires et les mouvements du tympan que déclenchent les variations de pression dans le conduit auditif externe. Résultats et conclusions: Qu’il s’agisse de variations de pression lentes ou rapides (entre –600 et +400 daPa), de l’oreille saine ou déficiente, l’ENG n’a révélé aucun nystagmus. En revanche, les enregistrements posturographiques des réactions vestibulo-spinales sur la plate-forme de mesure de Lucerne ont été plus sensibles. L’allongement de la courbe de variation a montré des différences significatives entre l’oreille saine et déficiente, que ce soit lors de variations de pression rapides ou lentes. En conclusion, la précision de ce type d’examen se révèle nettement supérieure à celle de l’examen classique du signe de la fistule d’Hennebert (signe d’Hennebert). Le système vestibulo-spinal réagit apparemment de manière plus sensible que le système vestibulo-oculaire aux variations de pression du périlymphe. De plus, la relation que l’on a établie entre les mouvements du tympan dus aux variations de pression et les symptômes vestibulo-cochléaires pourrait expliquer les succès de la pose de diabolos chez certains patients souffrant de la maladie de Ménière. Ces diabolos empêchent les mouvements du tympan liés au changement de pression, évitant ainsi les mouvements du périlymphe. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Programa de Pós-Graduação em Engenharia Biomédica, 2016. / Alterações associadas ao envelhecimento e algumas doenças podem afetar o controle postural influenciando de maneira negativa a qualidade de vida das pessoas. Há muitos testes que podem ser utilizados para descrever o controle postural do ser humano, entretanto, ainda não há um consenso de quais são os melhores testes a serem empregados durante a avaliação para extrair informações relevantes da condição de equilíbrio do indivíduo. O objetivo deste estudo foi implementar um conjunto de dados público com resultados de avaliações qualitativas e quantitativas relacionadas ao equilíbrio do corpo humano e assim permitir que diferentes centros de pesquisa tenham acesso a dados de referência para comparação e análises em um mesmo conjunto de dados. O controle postural dos sujeitos foi avaliado pela técnica de posturografia utilizando uma plataforma de força e pelo Mini Balance Evaluation Systems Tests. No teste de posturografia, nós avaliamos os sujeitos durante a postura ereta quieta por 60 s em quatro diferentes condições posturais em que a informação visual e de superfície de apoio foram manipuladas: em superfície firme com olhos abertos, em superfície firme com olhos fechados, em superfície macia com olhos abertos, e em superfície macia com olhos fechados. Cada condição postural foi desempenhada três vezes por cada sujeitos e a ordem das condições posturais foi randomizada entre os sujeitos. Em adição, para melhor caracterizar os sujeitos nós empregamos os seguintes testes: Short Falls Efficacy Scale International, Questionário Internacional de Atividade Física ¿ versão curta, e Trail Making Test. Os sujeitos também foram entrevistados para coletar informações referentes às suas características socioculturais, demográficas e de saúde. O conjunto de dados compreende sinais da plataforma de força (dados brutos das forças, dos momentos de força, e dos centros de pressão) de 163 sujeitos e informações sobre os sujeitos, as condições de equilíbrio, e os resultados das demais avaliações. Este estudo está publicado em Santos DA, Duarte M. (2016) A public data set of human balance evaluations. PeerJ Preprints 4:e2162v1 https://doi.org/10.7287/peerj.preprints.2162v1. / Age-related disabilities and certain illnesses affect body balance in humans and can negatively influence their health and quality of life. There is a large variety of tests to describe balance in humans and there is no consensus yet on the best tests and their implementation details in order to extract meaningful information about subject¿s balance condition. The goal of this study was to create a public data set with results of qualitative and quantitative evaluations related to human balance to allow access of a normative reference for data comparison and testing analysis from different centers. Subject¿s balance was evaluated by posturography using a force platform and by the Mini Balance Evaluation Systems Tests. In the posturography test, we evaluated subjects during standing still for 60 s in four different conditions where vision and the standing surface were manipulated: on a rigid surface with eyes open; on a rigid surface with eyes closed; on an unstable surface with eyes open; on an unstable surface with eyes closed. Each condition was performed three times and the order of the conditions was randomized among subjects. In addition, the following tests were employed in order to better characterize each subject: Short Falls Efficacy Scale International; International Physical Activity Questionnaire Short Version; and Trail Making Test. The subjects were also interviewed to collect information about their socio-cultural, demographic, and health characteristics. The data set comprises signals from the force platform (raw data for the force, moments of forces, and centers of pressure) of 163 subjects and information about the subjects and balance conditions and the results of the other evaluations. The results of this study are also published in Santos DA, Duarte M. (2016) A public data set of human balance evaluations. PeerJ Preprints 4:e2162v1 https://doi.org/10.7287/peerj.preprints.2162v1.

Body balance is the ability people have to keep themselves erect or to perform acceleration movements and rotation without oscillation or fall. Balance alterations can happen due to a problem in one or more of the systems and then the person complain of imbalance. Parkinson s disease (PD) can be included among the multiple causes that lead to changes in body balance, considering that this disease is defined as a progressive neurological disorder, essentially with motor symptoms. The alterations in body balance cause resting tremor, rigidity, akinesia, failure of postural reflexes and walking and balance instability, among others. Thus, because of the close relationship between Parkinson's disease and vestibular and body balance changes, this study aims at evaluating body balance in Parkinson s patients. The study group contained twelve participants with Parkinson s disease, from the neurology sector at the University Hospital in Santa Maria. They were assessed based on anamnesis, static and dynamic balance tests, coordination, dynamic posturography and vestibular test. In order to compare the results from the dynamic posturography, there was a paired control group. Results: The main vestibular problems by Parkinson s patients were: balance problems (100,00%), dizziness (75,00%), imbalance while walking (75,00%), gait deviation (50,00%), tendency to fall (41,66%), vertigo (25,00%) and instability (25,00%); besides this, tremor (100,00%), rigidity and difficulty with movements (83,33%), problems to begin movements and problems with the gait(100,00%). Significant changes were found in Romberg-Barré, Untemberg and Walking tests, and there were 6 cases with normal vestibular examination, 4 with central vestibular syndrome and 2 cases of peripheral vestibular syndrome. In the dynamic posturography, it was verified balance instability if compared to the control group in terms of the Sensory Organization Test (SOT), in the average and the use of the vestibular system. Conclusion: The main vestibular complaints from Parkinson s patients are problems with balance, dizziness, imbalance while walking, gait deviation, tendency to fall, vertigo and instability. The dynamic posturography was more accurate to detect alterations in body balance than the vectoelectronistagmography. / O equilíbrio corporal é a capacidade do ser humano de manter-se ereto ou executar movimentos de aceleração e rotação do corpo sem oscilação ou queda. As alterações do equilíbrio podem ocorrer devido a alguma falha em um ou mais dos sistemas, levando o indivíduo a se queixar de desequilíbrio corporal. A doença de Parkinson (DP) pode estar entre as múltiplas causas que ocasionam alterações no equilíbrio corporal, a qual é definida como uma afecção neurológica progressiva, caracterizada essencialmente por sintomas motores. As decorrentes alterações no controle motor tornam-se notáveis, resultando em tremor de repouso, rigidez, acinesia, alteração dos reflexos posturais e distúrbios do equilíbrio e marcha, dentre outros sintomas. Desta forma, tendo em vista a estreita relação entre doença de Parkinson e as alterações vestibulares e do equilíbrio corporal, justifica-se a realização deste estudo, que tem como objetivo avaliar o equilíbrio corporal de indivíduos parkinsonianos. O grupo de estudo foi formado por doze indivíduos com diagnóstico de doença de Parkinson, atendidos no setor de Neurologia do Hospital Universitário de Santa Maria. Os parkinsonianos foram avaliados em função dos relatos da anamnese e achados na avaliação do equilíbrio estático e dinâmico, coordenação dos movimentos, posturografia dinâmica e exame vestibular. Para comparar os resultados da posturografia dinâmica foi utilizado um grupo controle pareado. Resultados: As principais queixas vestibulares relatadas por indivíduos portadores de doença de Parkinson foram: problemas com equilíbrio (100,00%), tontura (75,00%), perda do equilíbrio ao caminhar (75,00%), desvio na marcha (50,00%), tendência a cair (41,66%), vertigem (25,00%) e instabilidade (25,00%); acompanhados de tremor (100,00%), rigidez e dificuldade em realizar os movimentos (83,33%), dificuldade em iniciar os movimentos e na marcha (100,00%). Foram encontradas alterações significativas nas provas de Romberg-Barré, Untemberg e Marcha e seis casos apresentaram exame vestibular normal, quatro síndrome vestibular central e dois síndrome vestibular periférica. Na posturografia dinâmica verificou-se alteração no equilíbrio quando comparados ao grupo controle em todos os testes de organização sensorial, na média e na utilização do sistema vestibular. Conclusão: As principais queixas vestibulares relatadas por indivíduos portadores de doença de Parkinson são problemas com equilíbrio, tontura, perda do equilíbrio ao caminhar, desvio na marcha, tendência a cair, vertigem e instabilidade. Pacientes parkinsonianos apresentam alteração do equilíbrio corporal sendo que a posturografia dinâmica mostrou-se mais sensível para detectar as alterações de equilíbrio do que a vectoeletronistagmografia.

The corporal balance is fundamental to that the individual keeps his quality of life and get to do his daily life activities. The maintenance of the balance depends on three systems: the vision, the proprioceptive system and the vestibular system. Being multiple the corporal balance alterations causes, its diagnosis, not rare, constitute a challenge for the physician and the patient. On this way, being the Dynamic Posturography recognized like the most global form to observe the balance alterations, it becomes an excellent resource. Thus, the present work has as objective to study the Dynamic Posturography using the "Foam-Laser Dynamic Posturography" technique in individuals of different genders and ages variyng between 14 and 60 years old, in order to assist in a more accurate diagnosis of the balance disturbances, allowing to characterize its type and intensity in accordance with each individual. 204 individuals had been evaluated without corporal balance alteration complaints, being 97 of the female gender and 107 of the male gender. The individuals had been submitted to the evaluation using the Dynamic Posturografia "Foam-Laser". The results statiscally demonstrate a significant difference in the Organization Sensorial Test (SOT) in function of the individuals gender and ages, the women had presented better values in the most part of the SOT, in the different ages. It can be concluded that it has the necessity of values differentiated for SOT of the Dynamic Posturografia "Foam-Laser" between men and women in agreement with the age group. As well as, the accomplishment of new studies, that objectified the standardization of the Dynamic Posturografia "Foam-Laser", in function of the individuals gender and ages / O equilíbrio corporal é fundamental para que o indivíduo mantenha sua qualidade de vida e consiga exercer suas atividades de vida diárias. A manutenção do equilíbrio se dá por intermédio de três sistemas: a visão, o sistema proprioceptivo e o aparelho vestibular. Por serem múltiplas as causas das alterações do equilíbrio corporal, seu diagnóstico, não raramente, constitui um desafio para o clínico e o paciente. Dessa forma, a Posturografia Dinâmica ao ser reconhecida como a mais global forma de observar as desordens do equilíbrio, torna-se um relevante recurso. Assim, o presente trabalho tem como objetivo estudar a Posturografia Dinâmica por intermédio da técnica Foam-Laser Dynamic Posturography (CASTAGNO, 1994a) em indivíduos dos diferentes gêneros e faixas etárias entre 14 a 60 anos, a fim de auxiliar num diagnóstico mais preciso dos distúrbios do equilíbrio, permitindo caracterizar seu tipo e intensidade de acordo com cada indivíduo. Foram avaliados 204 indivíduos, que não apresentavam queixas de alteração no equilíbrio corporal, sendo 97 do gênero feminino e 107 do gênero masculino. Os indivíduos foram submetidos à avaliação por intermédio da Posturografia Dinâmica Foam- Laser . Os resultados demonstram diferença estatisticamente significante no Teste de Organização Sensorial (TOS) em função do gênero e da faixa etária dos indivíduos, evidenciouse também que as mulheres apresentaram valores melhores na maior parte do TOS, nas diferentes faixas etárias. Pode-se concluir que há a necessidade de valores diferenciados para o TOS da Posturografia Dinâmica Foam-Laser entre homens e mulheres de acordo com a faixa etária. Assim como, seria relevante a realização de novos estudos, que objetivassem a padronização da Posturografia Dinâmica Foam-Laser , em função do gênero e da faixa etária dos indivíduos
